Most SIMs charge extra when you go over your data. Chattr doesn't.
Why parents choose Chattr for kids
Kids use more data than most parents expect. Short videos, music, gaming, school apps, and chats all add up across the month — especially when they're away from Wi-Fi.
A capped plan might seem cheaper on paper, but the reality is different:
- YouTube at HD uses around 1.5GB per hour
- TikTok scrolling for 30 minutes a day adds up to ~15GB a month
- A single game download can use 2–3GB in minutes
- Going over the allowance can cost up to £10 per extra GB on some networks
Unlimited data removes all of this risk. One fixed price. No monitoring. No surprises. No arguments.
What kids actually use data for
| Activity | Per hour | 1hr/day monthly |
|---|---|---|
| YouTube (HD) | ~1.5GB | ~45GB |
| TikTok / Instagram | ~1GB | ~30GB |
| Online gaming | ~300MB | ~9GB |
| Music (Spotify) | ~460MB | ~14GB |
| Video calls | ~1.2GB | ~36GB |
A child who watches an hour of YouTube and scrolls TikTok for 30 minutes daily is already using over 50GB per month — before gaming or video calls.

Tips to stay in control
- Choose unlimited from the start. Starting on a capped plan and upgrading later means paying more during the transition. Unlimited from day one is simpler.
- Set rules for streaming quality. Encourage standard definition when on mobile data — it still looks fine and uses far less data.
- Download on Wi-Fi at home. Games, apps, and playlists downloaded on Wi-Fi avoid large unexpected mobile data use.
- Use device-level controls. Both iOS and Android have screen time and content controls that work alongside an unlimited SIM.
